Is there a Z Stepper Adjustment?

[Taki8888]

Hi,

What is wrong with my Ender 6? It is stock unit, no BL touch. When I print 1/2" to 1" height, I start to hear the Nozzle scraping over the printed top layer.
It does this once it reaches a certain height. My bed is very leveled. This is very frustrating because I attempted many times to print a figurine and I use structure supports on the finger tips.

The nozzle would knock off the structure supports every time during the printing. I also added brims and it still knocks off the brims from the surface. It is not the surface bed or nozzle height.

It has something to do with the Z stepper motor? The bed is not lowering quite enough so the nozzle ends up hitting the top layer?

Any ideas? I'm stuck now and don't know how to resolve this.
